Why not get the molecular structure for oxygen? Kind of a nerdy tattoo but really unique. People would ask you about it all the time. It looks similar to this but not quite. I couldn't find the actual symbol for oxygen but any science nerd would like to help you out. http://upload.wikimedia.org/wikipedia/coNeed tattoo ideas for something that symbolizing what a you need to live or to be happy?
The worst case scenario is finding your ink on someone else.



Go to a website like http://www.theartoftattoo.net where they offer you thousands of designs for twenty bucks. It is not free but it is pretty damn close.



I sincerely hope that this helps you and would hope that you can choose me as a best answer since I am new and need the points.
symbol of peace.

A heart to represent love.
